Foca is a FT232RL breakout. The FT232RL is a USB to serial UART interface with optional clock generator output. It’s the essential tools for establishing communication between PC and mostly MCU. Especially, it’s the optimum tool for basic boards without without USB interface, like arduino pro, colorduino, etc.
The good point is that it also...
This is a power module for the standard bread boards (Small and Medium sized). It's concave design so will not wast your proto zone. It also supports both 5v and 3.3v (both can be enabled on each power rail).
We think it is a must to have on your workbench, really.
It's a small USB to TTL serial tool, using the PL2303 chip.
You can use it to connect some serial device to your PC via USB port, an avr, an msp430 or an stm32 for example.
It's very cheap compared to the ft232 alternative and works very well, up to more than 1mbit/s.
BTBee is an easy to use Bluetooth SPP module compatible with existing Xbee sockets, designed for transparent wireless serial connection setup. It can directly plug into the Bee sockets and use the UART port for Bluetooth communication.
This module uses the newest 2.4GHz transceiver from Nordic Semiconductor, the nRF24L01+.This transceiver IC operates in the 2.4GHz band and has many new features! Take all the coolness of the nRF2401+ and add some extra pipelines, buffers, and an auto-retransmit feature.
This is a long distance 2.4G wireless module which basic on nRF24L01+ chip, and there is the PA and LNA circuit on board, with the external antenna it can reach long distance than the one without these parts.
This is a breakout board for Freescale's MMA7361L three-axis analog accelerometer. The sensor requires a very low amount of power and has a g-select input which switches the accelerometer between ±1.5g and ±6g measurement ranges. Other features include a sleep mode, signal conditioning, a 1-pole low pass filter, temperature compensation, self test, and...
It's a small breakout board for the ENC28J60 Ethernet chip. Contains all the necessary hardware to implement an Ethernet interface including the isolation transformer and LINK/STATUS and power LEDs. SPI interface makes this one of the easiest 10Base-T ICs yet. It's 3.3V with 8KB buffer.
